“Einstein equation”的概念、定义、习题解题方法及翻译-物理辞典

单词	Einstein equation
释义	Einstein equation 1 The mass-energy relationship announced by Einstein in 1905 in the form E = mc², where E is a quantity of energy, m its mass, and c is the speed of light. It presents the concept that energy possesses mass. See also relativity. 2 The relationship E_max = hf - W, where E_max is the maximum kinetic energy of electrons emitted in the photoemissive effect, h is the Planck constant, f the frequency of the incident radiation, and W the work function of the emitter. This is also written E_max = hf - φe, where e is the electronic charge and φ a potential difference, also called the work function. (Sometimes W and φ are distinguished as work function energy and work function potential .) The equation can also be applied to photoemission from gases, when it has the form: E = hf - I, where I is the ionization potential of the gas.
